APC crashes when user cache is used

I'm developing a PHP app and and want to cache some data in APC. APC is running and enabled, I can see statistics when I open apc.php which indicate that opcode caching works fine.

However, the apache process crashes whenever I try to use apc_store() or apc_add() to store some data.

This is on a Windows 7 Professional 64bit system and happens with both of these version combinations:

With the first configuration, the crash happens immediately and this in the apache error log:

[Fri Jun 08 12:51:58 2012] [notice] Parent: child process exited with status 255 -- Restarting.

With second there is some delay and I get this:

[Fri Jun 08 16:18:48 2012] [notice] Child 5052: Exit event signaled. Child process is ending.
[Fri Jun 08 16:18:48 2012] [warn] (OS 995)Der E/A-Vorgang wurde wegen eines Threadendes oder einer Anwendungsanforderung abgebrochen.  : winnt_accept: Asynchronous AcceptEx failed.
[Fri Jun 08 16:18:48 2012] [warn] (OS 10038)Ein Vorgang bezog sich auf ein Objekt, das kein Socket ist.  : setsockopt(SO_UPDATE_ACCEPT_CONTEXT) failed.
[Fri Jun 08 16:18:52 2012] [warn] pid file C:/wamp/bin/apache/apache2.2.22/logs/httpd.pid overwritten -- Unclean shutdown of previous Apache run?
[Fri Jun 08 16:18:52 2012] [notice] Apache/2.2.22 (Win64) PHP/5.3.13 configured -- resuming normal operations

What can be done to fix this?

Seems like the array I wanted to store contained a native resource, and that caused the crash.

Using serialize() before storing it and unserialize() afterwards fixed the problem.
